We pray for one last landingOn the globe that gave us birth;Let us rest our eyes on fleecy skiesAnd the cool green hills of Earth.

We chase misprinted liesWe face the path of timeAnd yet I fightAnd yet I fightThis battle all aloneNo one to cry toNo place to call home

Don't stand beside my grave and weep,For I'm not there, I do not sleep,I am a thousand winds that blow,I am the diamond's glint on snow,I am the sunlight on ripened grain,I am the gentle autumn's rain.When you awaken in morning's hush,I am the swift uplifting rush,of quiet birds in circle flight,I am soft stars that shine at night,Don't stand beside my grave and cry,I am not there. I did not die.

There is a silence where hath been no soundThere is a silence where no sound may beIn the cold grave, under the deep deep sea

As Eternity has reckonedThere's a lifetime in a second.

Sweet is love when all is saneSweet is death to rid the painCruel is death when all is wellCruel is love when all is hell

Cold hearted orb that rules the night,Removes the colours from our sightRed is grey, and yellow whiteBut we decide which is right.And which is an illusion.Pinprick holes in a colourless sky,Let incipient figures of light pass by,The mighty light of ten thousand suns,Challanges infinity and is soon gone.Night time, to some, a brief interlude,To others, the fear of solititude.Brave Helios, wake up your steeds,Bring us the warmth the countryside needs.

I know someday you'll have a beautiful lifeI know you'll be a star, in somebody else's skyBut why, why, why can't it be mine?

The woods are lovely, dark, and deep,But I have promises to keep,And miles to go before I sleep,And miles to go before I sleep.

If you love something, let it go.If it comes back to you, it's yours.If it doesn't, it never was.

Some say the world will end in fire,Some say in ice.From what I've tasted of desireI hold with those who favor fire.But if it had to perish twice,I think I know enough of hateTo say that for destruction iceIs also greatAnd would suffice.

The discoveries of Michael Faraday formed the foundation of electric motor technology.However, it was not until the 19th century that research into the subject started to intensify. Notable developments in this century include the work of Georg Ohm, who in 1827 quantified the relationship between the electric current and potential difference in a conductor, Michael Faraday, the discoverer of electromagnetic induction in 1831, and James Clerk Maxwell, who in 1873 published a unified theory of electricity and magnetism in his treatise Electricity and Magnetism.

Electricity has been a subject of scientific interest since at least the early 17th century. The first electrical engineer was probably William Gilbert who designed the versorium: a device that detected the presence of statically charged objects. He was also the first to draw a clear distinction between magnetism and static electricity and is credited with establishing the term electricity. In 1775 Alessandro Volta's scientific experimentations devised the electrophorus, a device that produced a static electric charge, and by 1800 Volta developed the voltaic pile, a forerunner of the electric battery.Thomas Edison built the world's first large-scale electrical supply network.

Nikola Tesla made long-distance electrical transmission networks possible.During this period, the work concerning electrical engineering increased dramatically. In 1882, Edison switched on the world's first large-scale electrical supply network that provided 110 volts direct current to fifty-nine customers in lower Manhattan. In 1884 Sir Charles Parsons invented the steam turbine which today generates about 80 percent of the electric power in the world using a variety of heat sources. In 1887, Nikola Tesla filed a number of patents related to a competing form of power distribution known as alternating current. In the following years a bitter rivalry between Tesla and Edison, known as the "War of Currents", took place over the preferred method of distribution. AC eventually replaced DC for generation and power distribution, enormously extending the range and improving the safety and efficiency of power distribution.
The efforts of the two did much to further electrical engineering—Tesla's work on induction motors and polyphase systems influenced the field for years to come, while Edison's work on telegraphy and his development of the stock ticker proved lucrative for his company, which ultimately became General Electric. However, by the end of the 19th century, other key figures in the progress of electrical engineering were beginning to emerge. The Darmstadt University of Technology founded the first chair and the first faculty of electrical engineering worldwide in 1882. In the same year, under Professor Charles Cross, the Massachusetts Institute of Technology began offering the first option of Electrical Engineering within a physics department. In 1883 Darmstadt University of Technology and Cornell University introduced the world's first courses of study in electrical engineering, and in 1885 the University College London founded the first chair of electrical engineering in the United Kingdom. The University of Missourisubsequently established the first department of electrical engineering in the United States in 1886.
